of sea ice retreat on the entire ocean system from the surface to the deep sea. Eleven years ago, Antje Boetius was part of the largest ever sea ice minumum in the Arctic and its consequences for life in [...] the North Pole. For two months, a good fifty scientific expedition participants will explore the Arctic in transition as sea ice extent reaches its annual minimum in September. They will explore the biology [...] in the deep sea. Now she is returning with her team to compare the state of the Arctic today - also with the data from the MOSAiC expedition 2019/20.

Due to intensifying sea-ice melting in the Arctic, sunlight is now penetrating deeper and deeper into the ocean. Since marine zooplankton respond to the available light, this is also changing their behaviour

The role of clouds and warm air masses from the open ocean for the rapid warming of the Arctic is at the heart of a recent Alfred Wegener Institute project on Svalbard. The researchers are applying a new

They have now published three overview articles on the MOSAiC atmosphere, snow and sea ice, and ocean programs in the journal Elementa, highlighting [...] together. These results present the first complete picture of the climate processes in the central Arctic which is warming more than two times as fast as the rest of the planet - processes which affect weather
